Abstract

In this paper, we explore the laser properties of a 2.1 µm Ho:LaF3 laser intracavity pumped by a LD-pumped Tm:YLF laser. Ho:LaF3 crystals, with a doping concentration of 2%, have been verified as a novel type of laser gain material, whose luminescence lifetime of the 5I7 level was up to 25.7 ms. The Ho:LaF3 laser achieved an average output power of 2.07 W with a slope efficiency of 16.2%. The dual-wavelength output centered at 2089 nm and 2093 nm and exhibited excellent spot quality with M2x and M2y values of 1.19 and 1.23, respectively. Our results effectively demonstrate the impressive capability of Ho:LaF3 crystals for generating high-power 2.1 µm mid-infrared lasers.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
